6 Claims.

The present invention pertains to a novel receptacle and particularly to an appliance thereto for discharging the contents. The invention is applicable especially to containers of paste and powder such as tooth paste, tooth powder, face powder; soap powder and the like. The invention is useful in connection with a permanently supported receptacle or one that is comparatively small and usually held in the hand, such as a tube of tooth paste or a can of tooth powder.

The invention embodies generally a ported closure adjacent to which is slidably mounted a ported valve plate. 'Ihe twoy ports or openings are ladapted to register to provide a free outlet from the receptacle but are normally closed with respect to each other through the action of a spring tending to move the valve plate rearwardly or to the closed position.

More specifically, an object of the invention is to direct sluggish or compressible materials, such as powders and pastes, towards the outlet and to prevent them from being compressed and accumulated into the ports of the closure and valve plate. This object is accomplished by means of an enlargement formed on the valve plate at the rear end of the opening therein, and providing this enlargement with a surface sloping from the rear end of said port in the forward direction and away from the closure. The sloped surface acts as a wedge that forces material to and through vthe registering ports when the valve plate is moved forward. By this means, not only is the material positively fed through the ports but is prevented from com- 35y pressing or otherwise accumulating therein to interfere with the free action to the device.

The invention further embodies a simple and convenient'means for normally closing the ports as above stated. A stem extends rearwardly from 40 the enlargement and through the wall of the receptacle and is formed externally with a button.

A coil spring is mounted between the button and the receptacle and is tensioned to draw the valve plate rearwardly to its closed position. The valve plate is movedforwardly to open position by manual pressure of the buttonfagainst the action of the spring.

The invention is fully disclosed by way of exl50p-ample by the following description and in the accompanying drawing, in which Figure 1 is al longitudinal section of the closure end of the device in open position;

Figure 2 is a similar section of the device in closed position;

Figure 3 is a plan View of the closure end;

Figure 4 is asidev elevation, and j y Figure 5 is a section on the line 5-5 of Fig-` ure l.

Reference to these views will now `be made by use of like characters that are employed to designate corresponding parts throughout.

ln Figures 1 and 2, the numeral l designates the body of a receptacle for toothpowder, face powder, soap powder or the like. The receptacle may be a wall receptacle which is usually mounted with its outlet downward, as illustrated herein, or it may be a small container held inv the hand, such as atube of tooth paste or a canof tooth powder. Accordingly, the end illustrated in the several gures may be either the top or the bottom of the receptacle, according to the position in' which it is held. For the purpose of description, it will be identied as the closure end. l

The closure end of the receptacle is preferably reduced in the form of a neck 2 which may be circular, square or of any other desired shape. Across the free extremity ofthe neck is formed` a closure plate 3 eitheras a separate member attached thereto or a part integral therewith. 'I'he only outlet from the container through the plate 3 is an opening# through the plate as clearly illustrated in Figures l, 2 and 3.

On the inner surface of the closure 3 is slidably mounted a valve plate 5. The valve plate 5-is guided at one end in a slot 6 formed in the neck 2. The opposite end of the plate is enlarged at 1 and has attached thereto a stem 8 slidable in the neck 2 at a point opposite the slot 6. The outer exremity of the stein 8 carries a button 9, and between the button and the neck is a tension spring l0 for a purpose that will presently be described. l

An Aopening I I is formed in the valve platel 5` between the enlargement l and the slot 6l and immediately adjacent to the enlargement as clearly shown in Figures l and 2. This opening is of the same size as the opening and adapted to register therewith on pushing the button 9, whereupon ,a free outlet from the interior of the container is formed. The spring l0 normally expands on release of pressure at the button, whereupon the stem 8 and the plate 5 are retracted to the position shown in Figure 2 where the'openf ings 4 and Il are closed respectively by the vmembers 5`and 3.-

For the purposes of description, the movement of the valve plate 5 in the open position shown in Figure 1 will be considered the forward movement, and the enlargement 'I will -be regarded as being formed on the rear end of the valve plate. The Yforward space of the enlargement- 1 is sloped at I2 away from the closure 3 and in the forward direction. From the upper end of the slope, the thickness of the enlargement is gradually reduced as indicated by the numeral I3, thereby correspondingly reducing the resistance of the enlargement to rearward movement and also reducing the packing and compression of the contents between the rear end of the enlargement and the rear side of the neck 2.

The contents of the receptacle may be dense, sluggish or subject to packing. If the plate were uniformly of its minimum thickness, it would slide through the material without directing any of it towards the openings 4 and I I .Y The material might be so sluggish, dense or compressed as not to flow through the openings, at least not freely. 'I'he particular slope of the surface I2, as above described, is such as to direct material towards the openings when the valve plate is moved forward. The slope is important, inasmuch as a mere perpendicular Vsurface or a surface sloping in the opposite direction would either compress the material or move through it without directing material towards the openings.

The action of the slope I2 in directing material to and through the openings accomplishes not only this function but further maintains the openings free of accumulations of packed material that might otherwise fill the openings or interfere with the movement of the valve plate 5 toprevent complete covering of the openings.

Although a specific embodiment of the invention has been illustrated and described, it will be understood `that various alterations in the de- Iails of construction may be made withoutdeparting from the scope of the invention, as indicated by the appended claims.
